Abstract
The utility model relates to a disposable medical appliance, and is especially suitable for nursing operation of drainage after surgery operation of thoracic cavities and abdominal cavities. The utility model is composed of a trocar of a sidewall open slot, a drainage tube, a negative pressure device, a three-way valve which plays the regulating effect and a governor valve. Primary elements adopt disposable plastic products. The utility model has the advantages of convenient use, simple operation and high automatization degree. Patients can take free postural drainage.
Description
This utility model belongs to a kind of medical apparatus and instruments, is specially adapted to do the splanchnocoel puncture drainage and handles.
The splanchnocoel puncture drainage also does that the medicine filling is surgical operation processing operation commonly used in the splanchnocoel.Because the existence of the head of putting that let the acupuncture needle remain at a certain point usually makes patient can not take free position, and the interior visceral organ injury that often causes with cough.Often the deficiency because of the drain negative pressure makes nursery work loaded down with trivial details in the drain process, has increased the nursing difficulty.How further improving existing apparatus, making it can adapt to safe, convenient, high-quality, operation efficiently is anxious problem to be solved in the present surgical nursing work.
The purpose of this utility model promptly provides a kind of disposable remain-type sealing drainage system, make it put the free position that stays thing no longer to hinder the patient, can not cause stabbing of interior internal organs, and can finish drain and injection operation easily, realize regulating automatically the speed stabilizing drain, to improve its clinical care level.
Design of the present utility model has been taked following key measure, common puncture needle changed into do not have the bushing type of needle stand syringe needle, syringe needle tube wall upper edge axially processes groove one, drainage tube (or claiming to put the stream pipe) adopts flexible plastic or high-quality medical grade silicon rubber to make from the sleeve pipe syringe needle and penetrates, and the other end is connected to negative pressure device by three-way valve.Can finish puncture during application, the trocar is arrived at estimate the position, then promptly drainage tube that the trocar is withdrawed from is external, this moment, three-way valve made whole device be closed state, by the groove on the trocar sidewall trocar is resigned from office then, just realized that soft drainage tube puts the operation of staying.Crossover tee is connected its drainage tube and negative pressure device then, can realize drain.Can in body cavity, inject medicine by the three way cock after threeway turns to, realize conventional operations.
How further specify the purpose of this utility model below in conjunction with accompanying drawing realizes:
Fig. 1 is the structural representation that is this device.
Wherein 1 is the trocar, and 1A is a groove, and 2 is drainage tube, and 3 is three-way valve, and 4 is governor valve, and 5 is the negative pressure capsule, and 5A is a pressing spring, and 5B is the drain air inlet.
As can be seen, negative pressure device is to have adopted automatic negative-pressure capsule 5 from accompanying drawing 1, and its crust is the tub that flexible plastic is made, in a pressing spring 5A is arranged.This spring freely draws makes this capsule have maximum volume when growing to maximum, under drain air inlet 5B closed state, just form negative pressure in the capsule naturally, thereby cause the drain in the splanchnocoel to be sucked out.This air inlet 5B is connected with drainage tube 2, can be easy to realize drain continuously automatically.Can realize this automatic operating process well by governor valve 4 and need not labor management.Wherein the trocar 1, drainage tube 2, three-way valve 3 and negative pressure capsule 5 all can adopt disposable elements, can avoid cross infection so again, have simplified and reduced nursing staff's labor intensity greatly.
Through the sample clinical practice, patient's level of comfort improves greatly, and it is convenient to use, and simplified control is adapted at applying in the surgical postoperative nursing.
